Been on this site many times during my swap so I hope to find some help.
Story first, so you all know Exactly whats going on.
I have a rb25det in my S13 swapped in perfectly. Fully rebuilt the motor.(Crank, Rods, and Cams are the only stock internals) Did a 30 min. Initial driveway start-up.No problems, No check engine light. Then I went for a test drive. Did a 5 min under 45 MPH cruise, accelerated/idled normally for a long while and then all the sudden it falls flat on its face and couldn't stay alive for a second no matter how many times I tried. Got it home and went over every square inch of wire in the engine bay. ECCS and Fuel relay working and I have spark and fuel (35 psi). CAS tested perfect. Was running, and better than a brand new car too, so I know the wiring's not wrong. Here's where I get confused... When I pulled the plug off the MAF sensor it fired right up. Tested the MAF and the voltage was .2 instead of the .8 FSM specs. Bought a new one and its a perfect .8. Went to plug it in and start it up and I get nothing. Same problem as before. This is driving me crazy, PLEASE HELP if any of you know the answer. :dead:
